Hi all, Ihave this Linux shell script which gets an Azure Web token
#!/usr/bin/bash
clear
CLIENTID=41eeebbd-ea7f-4f49-a936-1624b6cb9c72
CLIENTSECRET=UIC8Q~nj3cDetR4XQlSNbm19WpywweJMi.CuwbGA
RESOURCE=api://41eeebbd-ea7f-4f49-a936-1624b6cb9c72
TENANTID=90fff3ee-9a7c-4eb1-8259-4d8c6bf6ca90
AZURESITE="https://login.microsoftonline.com/$TENANTID/oauth2/token"
FLAGS="-s -d"
CURL="curl $FLAGS"
COMMANDLINE="$CURL grant_type=client_credentials&client_id=$CLIENTID&client_secret=$CLIENTSECRET&resource=$RESOURCE"
ACCESSTOKEN=$($COMMANDLINE $AZURESITE)
ACCESSTOKEN=$(echo $ACCESSTOKEN|jq .access_token)
ACCESSTOKEN=$(echo $ACCESSTOKEN|sed s/\"//g)
export ACCESSTOKEN
echo $ACCESSTOKEN

I would like to create an equivalent batch file in Windows

What I have tried:

@echo off
setlocal

set CLIENTID=41eeebbd-ea7f-4f49-a936-1624b6cb9c72
set CLIENTSECRET=UIC8Q~nj3cDetR4XQlSNbm19WpywweJMi.CuwbGA
set RESOURCE=api://41eeebbd-ea7f-4f49-a936-1624b6cb9c72
set TENANTID=90fff3ee-9a7c-4eb1-8259-4d8c6bf6ca90
set AZURESITE=https://login.microsoftonline.com/%TENANTID%/oauth2/token
set COMMANDLINE="curl -s grant_type=client_credentials&client_id=%CLIENTID%&client_secret=%CLIENTSECRET%&resource=%RESOURCE%"
echo "Command line is %COMMANDLINE%"

It bombs on the set COMMANDLINE= line with the error 'client_id' is not recognized as an internal or external command - followed by a similar error for client_id etc...
Any idea why guys ?

The & character in a CMD Prompt is command separator. It says "execute the command on the left of the & character, then execute the command to the right of the & when the left command has completed execution".

To get CMD to process that character as part of the URL, you would have to escape the & characters by preceding them with the ^ character:
@echo off
setlocal

set CLIENTID=41eeebbd-ea7f-4f49-a936-1624b6cb9c72
set CLIENTSECRET=UIC8Q~nj3cDetR4XQlSNbm19WpywweJMi.CuwbGA
set RESOURCE=api://41eeebbd-ea7f-4f49-a936-1624b6cb9c72
set TENANTID=90fff3ee-9a7c-4eb1-8259-4d8c6bf6ca90
set AZURESITE=https://login.microsoftonline.com/%TENANTID%/oauth2/token
set COMMANDLINE="curl -s grant_type=client_credentials^&client_id=%CLIENTID%^&client_secret=%CLIENTSECRET%^&resource=%RESOURCE%"
echo "Command line is %COMMANDLINE%"

The & in a Windows command is used to allow multiple commands on the same line. So client_id after the first one looks like the next command. You need the entire parameter string in double quotes, so try something like:
BAT
set CMDPARAMS="grant_type=client_credentials&client_id=%CLIENTID%&client_secret=%CLIENTSECRET%&resource=%RESOURCE%"
curl -s "%CMDPARAMS%"

Thanks to all of you I now have this
@echo off
set CLIENTID=41eeebbd-ea7f-4f49-a936-1624b6cb9c72
set CLIENTSECRET=UIC8Q~nj3cDetR4XQlSNbm19WpywweJMi.CuwbGA
set RESOURCE=api://41eeebbd-ea7f-4f49-a936-1624b6cb9c72
set CLIENTID=41eeebbd-ea7f-4f49-a936-1624b6cb9c72
set CLIENTSECRET=UIC8Q~nj3cDetR4XQlSNbm19WpywweJMi.CuwbGA
set RESOURCE=api://41eeebbd-ea7f-4f49-a936-1624b6cb9c72
set TENANTID=90fff3ee-9a7c-4eb1-8259-4d8c6bf6ca90
set AZURESITE="https://login.microsoftonline.com/%TENANTID%/oauth2/token"
set FLAGS="-s -d"
set CURL="curl %FLAGS%"
set COMMANDLINE="curl -v grant_type=client_credentials^&client_id=%CLIENTID%^&client_secret=%CLIENTSECRET%^&resource=%RESOURCE%"

rem How do I execute the line below ?
rem it expands to this

curl -s grant_type=client_credentials^&client_id=41eeebbd-ea7f-4f49-a936-1624b6cb9c72^&client_secret=UIC8Q~nj3cDetR4XQlSNbm19WpywweJMi.CuwbGA^&resource=api://41eeebbd-ea7f-4f49-a936-1624b6cb9c72 https://login.microsoftonline.com/90fff3ee-9a7c-4eb1-8259-4d8c6bf6ca90/oauth2/token

rem but when executed produces lots of markup but no token
set ACCESSTOKEN=%COMMANDLINE% %AZURESITE% 

set ACCESSTOKEN=echo %ACCESSTOKEN%|jq .access_token
echo %ACCESSTOKEN%
rem set ACCESSTOKEN=echo %ACCESSTOKEN%|C:\MinGW\git\usr\bin\sed.exe s/\"//g
rem echo %ACCESSTOKEN%

I don't know curl, but looking at curl - How To Use[^] I think the final command should be something like:
curl -d "grant_type=client_credentials^&client_id=%CLIENTID%^&client_secret=%CLIENTSECRET%^&resource=%RESOURCE%" %AZURESITE%

The -s (silent) and -v (verbose) options may be necessary, but I would suggest only one at a time. It may also be necessary to capture the output to a file, but I leave that to you.

If I set all the vars from the command line and run this
curl -s -d "grant_type=client_credentials&client_id=%CLIENTID%&client_secret=%CLIENTSECRET%&resource=%RESOURCE%" %AZURESITE%|jq .access_token

it works ( notice I've removed the ^ escape character ) but it still errors out in the batch file.

The beautiful output

Pete, can you add all the details to your question please? The formatting in the comments section is a mess still.

Hi Richard , I agree it is a mess but I don't know how to add things to the original question
